2019 Cadillac XT5 Steering Problems

“We got the message that our steering may be impacted and then our temperature gauge wasn’t working nor the stop/start feature. Trip to service dealer resulted in a $1,186.14 repair for the replacement of the thermostat. This car only has 37,269 miles. We were told by service tech this is a common issue in GM models and this year of car. This was a financial hardship on us and our well maintained, and rarely used, vehicle. How can GM know this is an issue and not offer remedy thru a recall?”

“While traveling home to Louisiana from a vacation, I noticed the engine temperature what stuck on Cold. We also were experiencing loss of power steering, and loss of AC in the car. We stopped at AutoZone in Destin, FL where they completed their FixFinder which reported the thermostat needed to be replaced, being it was stuck in the open position and wasn't properly gauging the engine temperature.

“My 2019 Cadillac XT5 has repeatedly shuddered at highway speeds since shortly after purchase on July 25, 2026. It occurs around 61–62 mph while maintaining speed before accelerating. The cause is UNKNOWN. The selling dealership evaluated the vehicle and performed a front-wheel alignment, but the shuddering persists.

The vehicle has also displayed a “Steering Assist Is Reduced—Drive With Care” warning and a check-engine light. …”

“The vehicle has approximately 40,000 miles. The thermostat and/or coolant temperature sensor malfunctioned, causing the warning message “Steering Assist Is Reduced, Drive With Care” to appear. This condition raises a safety concern because the malfunction affects or appears to affect the vehicle’s steering-assist system and could make the vehicle more difficult to safely control. I believe this issue warrants investigation by NHTSA and consideration for a safety recall.”

“The contact owns a 2019 Cadillac XT5. The contact stated that while his wife was driving approximately 20 MPH, the brake warning light illuminated. A message Steering Power Reduced was displayed before the steering wheel became difficult to turn in either direction. The contact stated that one day prior to the failure, the low power steering fluid warning light was illuminated, and the brake fluid was refilled. The contact stated after picking their children from school, the failure occurred. The contact who is an independent mechanic, was able to replicate the failure. …”
